Abstract

The invention relates to a closure for closing a vessel for holding liquid such as a fuel tank or the like. The closure includes a cylindrical, cup-shaped base body having an internal thread. The base wall of the base body has an inner wall surface on which a centrally aligned annular wall is formed. A flat sealing ring is arranged between the annular wall and the cylindrical wall. The sealing ring is arranged so as to have radial play with respect to the annular wall and a radially projecting insert is attached to the base wall of the base body. The insert has a side facing toward the base wall and includes a centering ring on this side which coacts with the annular wall to align the insert with respect to the base body. At least one attachment element is arranged within the centering ring and bridges the gap between the insert and the base wall. The insert is fixed to the base wall with the attachment element.
